Aside from the Poconos (which is gentrifying with the speed of a NYC neighborhood), the towns you are thinking of visiting work well. But I do have a suggestion.

First, some history and context:

State Parks: in the 1950s, Maurice Goddard made it his goal that every Pennsylvanian be within 25 miles of a state park and I think he got pretty close to that, so it depends what TYPE of state park you want (there is a subculture that, like Pokemon collecting, seeks to visit all the State Parks).

Crime: there are areas with higher rates of crime, but a lot of those rates come down to particular neighborhoods. For example: Philly has a certain reputation, but there are still low crime neighborhoods.

Internet: Comcast got its start in Philadelphia, so Comcast rules over most of us (and monopolies have no incentive to provide decent service). That being said, there are areas of fiber internet popping up.

NOW! With ALL of this, here is my suggestion: Belleville, PA. It recently got fiber internet, is close to the Lewistown Hospital (and other nursing homes/rehab facilities), is not too far from State College's shops, and there are a TON of Amish folk whose crimes are a bit more infrequent than the average group of people. It is VERY close to the Seven Mountains region that has multiple State Parks, natural areas, hiking trails, and scenic vistas. Belleville is located in a place called The Big Valley, and there are mountains all around.

I also believe Belleville is within your travel distance from those casinos.

Also, there is a REASON Belleville is called Belleville: it is so damn beautiful. I'm sure it has its problems (everywhere does) and while I don't live there nor is it my hometown, I still think it is a picturesque little mountain town

(Added bonus: mineral extraction will be limited to quarrying since Belleville is nestled in the folded mountains physiographic region. So no real need to worry about fracking or strip mining)
